WAVEFORM TRANSFER
WAVEFORM_SETUP, WFSU
Command/Query
DESCRIPTION
The WAVEFORM_SETUP command
specifies the amount of data in a waveform to
be transmitted to the controller. The command
controls the settings of the parameters listed
below.
Note:
FP
First point
SP
Sparsing
NP
The number of points
Sparsing (SP): The sparsing parameter defines
the interval between data points. For example:
SP = 0 sends all data points
SP = 1 sends all data points
SP = 4 sends every 4th data point
Number of points (NP): The number of points
parameter indicates how many points should be
transmitted. For example:
NP = 0 sends all data points
NP = 1 sends 1 data point
NP = 50 sends a maximum of 50 data points
NP = 1001 sends a maximum of 1001 data
points
First point (FP): The first point parameter
specifies the address of the first data point to
be sent. For waveforms acquired in sequence
mode, this refers to the relative address in the
given segment. For example:
FP = 0 corresponds to the first data point
FP = 1 corresponds to the second data point
FP = 5000 corresponds to data point 5001
The WAVEFORM_SETUP? query returns the
transfer parameters currently in use.
